Enzymatic and metabolic analysis of plants subjected to drought, heat, or a combination of drought and heat. A, malic enzyme activity and malate content; B, oxaloacetate, phosphoenolpyruvate, and pyruvate content; C, starch content; D, NADP concentrations, in control plants and plants subjected to drought, heat, or a combination of drought and heat for 6 h. Average rates and standard errors (n = 3) are shown for all experiments, letters and ^** indicate statistical significance (p < 0.05 and p < 0.01, respectively).
